Pretty cool idea from marketing and communications agency TBWA Belgium for its client, Pepsi: a ‘Like Machine’ that doesn’t accept money but gives people a free can of soda in exchange for a Facebook like.

It’s a step up from promo girls handing out free samples at intersections and shopping malls to random passersby, sure, but I’ll readily admit to cringing when I saw the guy enter his Facebook account details on the ‘social’ vending machine’s touch screen.

Would you log in and like a page for a free can of Pepsi?
